FIRE-HOSE NOZZLE SPECIFIOATION'forming' part of Letters Patent No. 597,182, dated January 11, 1898.

Application filed October 16, 1896. Serial No. 609,122. (No model.)

To all whom it may concern.-

Be it knownthat I, MILTON I-I. HART, of New York, in the county and State of New York, have invented certain new and useful Improvements in Nozzles for Fire-Hose, of which the following is a specification.

My invention relates to a compound or combination nozzle, so as to have either a straight stream or a spray-stream or what is called a chemical straight stream of small diameter. When one of these is in use the other is shut off.

I have shown in the drawing a longitudinal section of my nozzle.

a represents the nozzle provided for the f ullsize straight stream, having its orifice at a.

b is a nozzle provided with the two waterways 0 and cl.

c is a waterway or pipe for a spray-stream, having a head with orifices j j of diflr'erent degrees of pitch-that is, placed at diflierent angles to the axis of the nozzle 0.

cl is a waterway or pipe for conveying the small-sized straight stream. This waterway runs through the waterway or tube 12 without communicating or connecting with it and has an orifice or head independent of that provided for the pipe Z1.

e (shown in dotted lines) is a lever for turning the valve is, so as to open either of the two waterways a or sand close the other, It being the closing portion of the valve, by which the waterway a or c is opened or closed, as may be desired.

It isa valve for opening the tube cl, provided with the lever '5 and the stop f, which impinges against the stud g.

It will be seen that by the use of my improved nozzle either one of the three streams referred to may be used at pleasure and the others shut off.

What I claim, and desire to secure by Letters Patent, is

The improved combination-nozzle, consisting of the waterway a, for a straight stream; the waterway c, for a spray-stream the waterway d, for a smalhsized straight stream; the valve 7c, provided with the lever i; and the valve h and lever z; in combination, substantially as and for the purpose above described.
